Ctrl+Space is a standard keyboard shortcut for "Open location in inactive panel" - it's not a but IMO.

Perhaps the shortcuts for "Open location" and "Open location in inactive panel" could be customizable, but default shortcuts are good and useful. It's still possible to export items to main FC window and use standard shortcuts for selecting.

- Implemented: Option for search dialog to define in the section [fcSearchForm] of the file FreeCommander.find.ini: OpenLocationChangeShortcut=1 if the shortcut should be changed from Ctrl+Space to Alt+Space
